Testify brother!
BS34's need one thing: the cdn needle jets and needles (on the middle/3rd slot) to do 99% of whatever riding you're going to experience. Everything else stock.
If you go to a 2->1 exhaust pipe, *then* you need to start thinking about upping the main, because scavenging becomes a serious consideration with amount of valve overlap these things have.
Just wanted to stop in and say 'thanks'. Picked up an '80 Special that was sitting in a shed for who knows how long. Have gathered a wealth of information here on this site. Rebuilt the carburetors using the Canadian needles and jets but wasn't sure where to start for jetting using pod air filters. Sundie hit it right with the quote above. After some tuning, took it for a first ride around the block and it's running GREAT!
Now to build an engine stand, strip it down and get ready for a nice winter project. Thanks again for what everyone does here on the forum.
